There are numerous possibilities that could have been pursued but weren't, for various reasons. The following passage from The Crucible of War illustrates one, regarding the withdrawal of G-H from Bomber Command heavy bombers.
That may have been a strategic error of considerable consequence. Perhaps heavy bombers equipped with G-H should have been directed against German aircraft factories within its range in the fall of 1943. For although they understood the significance of electronic counter-measures in evading night-fighters, a number of officials at the Air Ministry argued such devices were nevertheless an unsatisfactory method of dealing with Bomber Command's main opponent. If enemy fighter strength grew, cautioned Air Vice-Marshal N.H. Bottomley, Harris would be 'unable to maintain the night offensive' no matter what jamming took place; and the DCAS therefore called for a sustained effort against aircraft manufacturing and assembly plants in Brunswick, Stuttgart, Hanover, Kassel, and Leverkusen, for example.
The director of bomber operations, now Air Commodore S. Bufton, vice Baker, concurred. Although he had not objected to the three operations against the German capital, hoping that Bomber Command could mount a successful repetition of the Hamburg raid 'on any industrial area, Berlin or anywhere else,' it was still essential that Harris 'start towards the specific targets [of Pointblank] eventually.' For if Bomber Command and the Americans did not between them destroy the Luftwaffe's capability to resist, he cautioned ominously, postwar analysts would regard the bombing offensive as a failure in their strategic employment of air power. Observing that it might be time to hold a conference with Harris and Eaker, Portal seemed to agree.
